I found out that ViaBTC is launching a token for those who want to manage large blocks of bitcoins. I was waiting for the full launch of the mining pool and planned to exchange my existing cryptocurrency for the new S9-BCC contract, hoping for a big profit in the future. Previously, I actively traded on this exchange, but now only bitcoin mining is available. There are also Dash and Litecoin, but I work exclusively with bitcoins since there is more demand and earning potential. I had to pay for the mining power - I rented several different ones as a trial for various terms. I started mining and hoped for a good profit. However, comparing my income to my expenses, I realize that my expectations are not being met. I will have to wait until the price of bitcoin goes up.
